Embodiment
Below in conjunction with the accompanying drawings, it is further elaborated with the utility model one of which embodiment.
As shown in figure 1, multi-rotor unmanned aerial vehicle of the present utility model includes central plate D, multiple is evenly distributed on central plate D weeks
The horn B enclosed, horn B are connected by folded piece C with central plate D, and motor and propeller are fixed with the end of each horn
A；Undercarriage E is provided with below central plate.
Referring to Fig. 2-7, multi-rotor unmanned aerial vehicle horn folded piece C of the present utility model passes through horn connector 1 and horn phase
Connect, including horn connector 1, spring 2, sliding part 3, locating part 4, fixture 5 and bearing pin 6, wherein,
